Reflection Loss

In telecommunications, reflection loss occurs on a line which results in part of the energy being reflected back to the source. This can occur:

  1. At a discontinuity or impedance mismatch, e.g. in a transmission line, the ratio of the incident power to the reflected power. Reflection loss is usually expressed in dB.
  2. In an optical fiber, the loss that takes place at any discontinuity of refractive index, especially at an air-glass interface such as a fiber endface, at which a fraction of the optical signal is reflected back toward the source. This reflection phenomenon is also called "Fresnel reflection loss," or simply "Fresnel loss."

... Because of this, it is convenient to set a baseline reflection loss (R.L.) that is deemed effective and determine the bandwidth within a given frequency that produces the desired reflection loss ... for this bandwidth determination is −10 dB, which corresponds to a loss of over 90% of the incoming wave ... University it was found that Fe filled MWNTs exhibited a maximum reflection loss of −22.73 dB and had a bandwidth of 4.22 GHz for a reflection loss of ...

Famous quotes containing the words loss and/or reflection:

    Perhaps it is a universal truth that the loss of liberty at home is to be charged to provisions against danger, real or pretended, from abroad.
    James Madison (1751–1836)

    Much of what passes for quality on British television is no more than a reflection of the narrow elite which controls it and has always thought that its tastes were synonymous with quality.
